I have been searching for GL-4 transmission oil for my oil change, and it’s quite pricey compared to GL-5. Is Triax Synergy Gear MT
75W-90 synthetic gear lube ($30 for 1 quart, pack of 2) suitable? It’s significantly cheaper than Red Line and other brands.
Appreciate any replies, links, or information on this.
Triax Synergy Gear MT 75W-90 synthetic gear lube should be fine for GL-4 applications, as it’s designed to meet GL-4 specifications. It’s a good alternative to more expensive brands like Red Line, especially if it’s significantly cheaper.
These awful American transmissions are also available in Europe. Bearing problems plagued the GM M32 gearbox in nearly every 2000s GM Opel, Alfa Brera, Fiat Punto, etc. As soon as thirty thousand miles, the gearbox had to be rebuilt.
You experience awful situations if you drive a shitty car.
For daily driving, only Mercedes and BMW are acceptable to me—only Nissan is acceptable for All-Terrain use. With 600,000 kilometers on the clock, my Terrano II is completely original. only minimal upkeep. I rebuilt a C180 and an E46 330i that I bought from junkyards.
Mate With almost 2500000 miles on all of them including my 2009 Audi A4, 2002 Passat, 2007 Renault Clio (for the wife), 2009 Volkswagen T5 Multivan, and 2009 Dacia Logan, I haven’t changed the gearbox oil on any of them.
If it were me, I’ would start by checking the owner’s manual for the scheduled maintenance recommendations to get a baseline.
It is important to remember that you are not just taking care of the gears; you are also maintaining the two shaft seals. Once these seals dry up and crack, the lubricant will start leaking slowly until the gears begin to make noise.
Six months ago, I bought an old truck from the 1990s, specifically choosing one with a manual transmission. It needed a fuel pump, and I discovered a mystery battery drain caused by an interior light switch on the door. I also had to replace the oil and filter, air filter, fuel filter, and two new tires.
I have a list of maintenance tasks, and this month I found a mechanic I trust. He is charging $170 to drain and fill the differential and manual transmission. If I were short on money, I’d change it myself every 100K miles, but I’m working steadily these days.
The truck either has 90K miles or 190K miles. Either way, it is about 30 years old. Given that I won’t be around in another 30 years, this is a good midpoint to refresh the gear lube and keep the shaft seals from drying out.
Hello guys, You can easily change the oil, but it is unlikely to solve any problems. Many vehicles with manual transmissions do not require transmission oil changes.
